Abstract
A method for processing a direct sequence spread spectrum signal, and a receiver for performing the method. A correlation is preformed between a received signal and the direct sequence used to determine peaks of different amplitudes. The spectrum of the information corresponding to the highest amplitude peak is respread using the direct sequence. The respread signal is subtracted from the received signal to create a new signal. This process is reiterated on the new signal until all of the peaks have been exhausted.
